DEMO_FRAMEMUL - Time-frequency localization by a Gabor multiplier

Description

This script creates several different time-frequency symbols and demonstrate their effect on a random, real input signal.

Cut a circle in the TF-plane

This figure shows the symbol (top plot, only the positive frequencies are displayed), the input random signal (bottom) and the output signal (middle).

Keep low frequencies (low-pass)

This figure shows the symbol (top plot, only the positive frequencies are displayed), the input random signal (bottom) and the output signal (middle).

Keep middle frequencies (band-pass)

This figure shows the symbol (top plot, only the positive frequencies are displayed), the input random signal (bottom) and the output signal (middle).
